Pag. 70. Linyphia eoncolor Westr.; p. 483. Theridion filipes 

 Blackw. — Of this species a paler variety occurs, in which the upper 

 part of the abdomen is of a greyish yellow colour tinged with greenish, 

 and exhibits a longitudinal, faintly ramified, blackish line along the 

 back; the belly is blackish. Mr Eisen has captured such a speci- 

 men at Valders in Norway. — From the posterior part of the vulva , 

 between the belly and the long, narrow, backward-directed process 

 which issues from the anterior border of the vulva and reaches at 

 least to the middle of the belly, proceeds in L. eoncolor another 

 similar, but much finer and shorter, backward directed stilus, which 

 is hidden by the larger process, and can only be seen when the 

 abdomen is viewed in profile. This stilus appears to have been over- 

 looked as well by Blackwall as Westring and Menge.
